Increasing the efficiency of defining the elements of traffic signalization cycle

Abstract

A new approach of defining the parameters of vehicle traffic and features of organizing the traf-fic flows (TF) monitoring to optimize the parameters of traffic signalization (TS) cycle has been considered. Goal. Increasing the efficiency of defining the elements of TS cycle and expanding the functionality of the common technique, receiving a full set of data to monitor and to control online the traffic at the intersection. Methodology. The method and the algorithm of defining the elements of TS cycle within the conditions of on-line changing the parameters of traffic flows and system adaptive response to a situation have been suggested. The possibilities of increasing the efficiency of measurements at the expense of multibeam laser scanning the intersection zone that provides increasing the accuracy of defining the cycle elements and cycle optimization have been analyzed. Results. It has been suggested to define the elements of regulation cycle accord-ing to accurate measurements to make possible reducing losses of time in the cycle and increas-ing the efficient operation time of phases. The developed structure of the device for implement-ing the suggested technique has been presented. The feasibility and sustainability of the algo-rithms included in this technique have been shown. Originality. The original innovative tech-nique of TF control at the signalized intersection patented in Ukraine has been suggested. Practical value. The advantages of our suggested technique have been presented. The additional op-tions of forecasting TF conditions at the intersection and criteria of TS quality control can be defined simultaneously in it. The flexible technique and integrated assessment of TS modes allow carrying out the combined adaptive control at the intersection in real time.
